The light intensity of a certain brand of light bulb is modeled by the function f(w) = 1.1w where w represents watts. which statement best describes the function? a) light intensity increases exponentially b) light intensity increases linearly c) light intensity is constant d) light intensity increases

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

the answer for this question is 38
